When I read this article, it confirmed everything that I have discussed with our clients in the past.  Up until now, everyone believes that the MAC OS is not able to get a virus.  Why would anyone think this?  Because it has not been a problem in the past?  The truth is, MAC has not really had a stronghold in the computer market before and now they are starting to take a little more ground.  The bigger they get in business computers, the more attackers will see them as a viable resource to attack.  I have been saying this for years.  Don’t get me wrong here, I think that MAC makes a good machine.  I do however think that they are much more limiting than a PC running Windows or some variation of Linux.  Take a look at this article and read for yourself.  I think this is just the beginning.
